One should follow a specific order to compile GCC, making sure that all dependencies are compiled properly. Some dependencies depend on others. In general the packages required to compile GCC properly are

Essential prerequisites:

Autoconf
Automake
M4

Direct Dependencies

GMP (requires -cxx option)
PPL (dep: GMP)
MPFR (dep: GMP)
MPC (dep: GMP, MPFR)
CLOOG-PPL (dep: GMP,PPL)

Install GMP first
============

./configure --prefix=/home/users/d/dr/droidzone/hostusr --enable-cxx

make ; make install[/code]


Install PPL next


============

PPL depends on GMP, so specify its location


./configure --prefix=/home/users/d/dr/droidzone/hostusr --with-gmp-prefix=/home/users/d/dr/droidzone/hostusr[/code]

make ; make install


Install MPFR


============


./configure --prefix=/home/users/d/dr/droidzone/hostusr --with-gmp=/home/users/d/dr/droidzone/hostusr

make ; make install[/code]


Now, Install MPC


================

Install MPFR and GMP first


, and then specify their path for MPC!


./configure --prefix=/home/users/d/dr/droidzone/hostusr --with-gmp=/home/users/d/dr/droidzone/hostusr --with-mpfr=/home/users/d/dr/droidzone/hostusr

make ; make install[/code]


Now, install CLOOG-PPL (For Graphite Loop Optimizations)


========================


./configure --prefix=/home/users/d/dr/droidzone/hostusr --with-gmp=/home/users/d/dr/droidzone/hostusr --with-ppl=/home/users/d/dr/droidzone/hostusr[/code]


Now, Install GCC


================


export LD_LIBRARY_PATH=/home/users/d/dr/droidzone/hostusr/lib:$LD_LIBRARY_PATH[/code]


./configure --prefix=/home/users/d/dr/droidzone/hostusr --with-gmp=/home/users/d/dr/droidzone/hostusr --with-ppl=/home/users/d/dr/droidzone/hostusr --with-cloog=/home/users/d/dr/droidzone/hostusr --with-mpc=/home/users/d/dr/droidzone/hostusr --with-mpfr=/home/users/d/dr/droidzone/hostusr --disable-multilib[/code]


Finally I found that GCC needs Glibc. Glibc needs Binutils!


Now, Install Binutils


================


./configure --prefix=/home/users/d/dr/droidzone/hostusr --with-gmp=/home/users/d/dr/droidzone/hostusr--with-ppl=/home/users/d/dr/droidzone/hostusr --with-cloog=/home/users/d/dr/droidzone/hostusr --with-mpc=/home/users/d/dr/droidzone/hostusr --with-mpfr=/home/users/d/dr/droidzone/hostusr

make ; make install

[/code]


You have to do a make clean if you get errors


Errors likely


However, with this, I got a specific error after around 10 minutes of building!

This means you had to pass LIB path.


Then I got another one..

FIX

===


./configure for gcc with --disable-multilib[/code]


./configure --prefix=/home/users/d/dr/droidzone/hostusr --with-gmp=/home/users/d/dr/droidzone/hostusr --with-ppl=/home/users/d/dr/droidzone/hostusr --with-cloog=/home/users/d/dr/droidzone/hostusr --with-mpc=/home/users/d/dr/droidzone/hostusr --with-mpfr=/home/users/d/dr/droidzone/hostusr --disable-multilib[/code]


For this, the following bit of information is useful:


Some other useful info:


Libraries have been installed in:

/home/users/d/dr/droidzone/hostusr/lib

If you ever happen to want to link against installed libraries

in a given directory, LIBDIR, you must either use libtool, and

specify the full pathname of the library, or use the `-LLIBDIR'

flag during linking and do at least one of the following:

- add LIBDIR to the `LD_LIBRARY_PATH' environment variable

during execution

- add LIBDIR to the `LD_RUN_PATH' environment variable

during linking

- use the `-Wl,-rpath -Wl,LIBDIR' linker flag

- have your system administrator add LIBDIR to `/etc/ld.so.conf'[/code]
